So this is legal in Commander, but [[Nearby Planet]] isn’t?
Yep, notably this doesn’t have all the basic land types like nearby planet does, which both means it can’t produce any color with a simple tap, and also means it doesn’t auto-fulfill all your domain with one land. It’s not strictly worse since Nearby has the Rupture Spire pay 1 clause, but Nearby is overall way more powerful assuming you can take advantage of domain-type abilities
Importantly just the third non-Vesuva/Stage/etc Locus for Cloudpost.
K so wait, can this count as one of your Urza lands for tron? Like the wording seems to say no but why specify those types then
